Question

The equivalent transform circuit contains an admittance of value ____ and equivalent transform current source.

(a) 1/L

(b) 1/sL

(c) L

(d) sL

The question was posed to me in unit test.

This intriguing question comes from The Concept of Complex Frequency topic in section S-Domain Analysis of Network Theory

Answer 1

Right answer is (b) 1/sL

Easy explanation: The time domain representation of inductor L has initial current iL(0^+). The equivalent transform circuit contains an admittance of value 1/sL and equivalent transform current source.
